I've got the functionality working as expected -- for example, select from an SSAS web part filter which then feeds values into a named range/parameter in a separate
Excel Web Services web part. Similarly I've got a choice filter feeding values to an SSRS report.

The problem is though, when I make the selection in the filter web parts, the value is not displayed when the page renders. In other words, I can pick "2008" in the SSAS filter, it feeds into the Excel Web Services..., BUT I do not see "2008" in the box associated with the SSAS filter, that box is simply blank. I can see what value I picked by selecting the filter icon again to the right of the box, and pulling up the select of selectable values however.

This seems to be the behavior irrespective of the type of filter. So my question is, is this standard behavior? You can pick a filter value, but it doesn't actually display when the page is rendered?
